SPECIFICATION forming part of Letters Patent No. 294,470, dated March 4', 1884:,V

Application filed January 2, 1883. (Model.) 4

STO all whom it may concern.:

Beit known that I, WARREN B. Howl-3, a citizen of the United States, residing vin Ohicago, in the county of Cook, State of Illinois, have invented a new and Vuseful folding-machi-ne for forming Wrappers for or upon suitable quantities of small merchandise for a packet, of which the following is a specification.

My invention relates to improvements in folding-machines 4for forming Wedge-shaped or prismatic-like wrappers for holding merchandise of various kinds-such as coffee, tea, starch, dried fruit, assorted candies, &c.but is particularly herein described as adapted for forming Wedge-shaped or prismatic-like packets consisting of small merchandise inclosed Within a flexible wrapper, and also more particularly for forming wedge-shaped or prismatic-like packets consisting of a flexible wrapper containing candy sticks or similarshaped articles of "merchandise The objects of my invention are to provide suitable mechanism, first, for closing down one end of the wrapper-blank, overlapping the other up'on the base of the packet, and holding these ends in place till the nishing flaps of the wrapper are formed and pressed; second, for folding in the sides of the wrapper-blank projecting from the ends of the die against the two ends of the male die when small merchandise is to be packed, or against the ends of the candy sticks when such `or-similar-shaped goods are to be packed, and at the same time creasing each of these projecting sides of the wrapper, 'so that they will stay inplace ready for the next folding third, for folding the remaining part of these two ends of the wrapper upon the part j ust folded, and at the same time forming finishing flaps of the wrapper by creasing and pressing them, and, finally, for closing the finishing iiaps one upon the other upon the base of the packet. I attain' these objects by the mechanism illustrated in the accompanying drawings, in which like letters of reference in the different gures indicate like parts.

Figure 1 representsa perspective upright view of a machine embodying my invention, the parts of which are in position to receive thewrapper and candy sticks to form a packet, and also represents by dotted lines the wrapv are means of adj usting folding-blades b b.

per in position and the gage properly set to receive the contents'of the packet, such as candy sticks and similar-shaped goods. Fig.

2 is a perspective upright view of my machine lcreased and pressed so thatv it will stay in place ready for the next folding. Fig. 3 is a perspective view of my machine containing the wrapper and candy sticks,with, the remaining sides of the two projecting ends of the wrapper closed upon the part just folded, as shown in Fig. 2, and the finishing-flaps formed and pressed into shape. AGage G is broken away in this view. Fig. et is a perspectiveview of the top part of my machine containing the wrapper and contents, vhaving Vone of the finishing-flaps folded down upon the base and the other Vin process of folding to nish the packet. Fig. 5 is a perspective view of the candy sticks to form a packet by my machine, having the Wrapper removed. Fig. is a perspective view of a packet with the folding of the wrapper carried to that stage shown in Fig. 2 of my machine. Fig. 7 isa perspective view ofthe packet with the fold- Vformed upon a male die, folded tothat-stage at which the die is to be removed, the goods to -be packed put inV its place and the packet completed. Fig. ll is a perspective view of a wrapper formed over a male die by means of my machine, to be nested with others for future use. Fig. 12 represents la sectional view of folding-wings E E, showingthe adjustable features in broken section. Fig. 13 represents an outer view of folding-wing E, showing plainly slot s, nut q, and screw q', which- Fig. 14 represents a view in detail ofvfolding-blade b, plate b2, lugs b3 b5, spiral spring b?, and screw j. Figui-5 represents an outer view of fold- IOO . ing-wings D D, showing means for adjusting blades D D.

A represents the frame of my machine, provided wit-h lugs, to which is hinged the gage G at g. Frame A is also provided with a rigid upright stop, H, (shown plainly in Fig. 3,) to operate as astop to cap F, the upper and center part of frame A being of such shape as to receive and hold the female die B. Frame A is also provided with a transverse pivothole just underneath the apex of the V-shaped female die B, for inserting the transverse pivot c, connecting rigidly the two operating-cams C C.

B represents the felnale die, open at the V- shaped ends, and mounted and suitably fastened upon the frame A, and provided with slides a a', adjustable by means of thumbscrews h h on both sides die B. Slide a is also provided with suitable attachments for spiral spring i, similar to attachment bi shown upon plate b, Fig. 14.

D D represent two folding-wings, hinged to female die B at d d, provided with foldingblades DIl D2, attached rigidly to folding-wings D D along the lines x y, x y, at a right angle with wings D D, for the purpose of pressing the folds of the wrapper along the lines Z t, lo, and Z ai, as shown in Fig. G, against the foldingwings E E, so that the wrapper will stay in place as folded, preparatory to the next folding, as shown plainly in Fig. 2. The foldingwings D D are also provided with blades D D', attached rigidly to folding-wings D D at an obtuse angle along the lines x .r w, for the purpose of creasing the wrapper along the lines a o, a z, as shown in Fig. 6, preparatory to forming the folds ofthe inishing-tlaps and pressing them into shape, as shown in Fig. 2, along the lines k x, k x, and x a", :v x. Blades D D may be made adjustable, when it is desired to adapt the machine to fold differentsized packets, by means of slides provided with screw and nut passing into corrugated slots in folding-wings D D, as shown in Fig. 15, i'n which p represents a slide rigidly attached to blades D -D, ineased within the face of folding-wings D D, and provided with screw q and nut q, which are adapted to pass through and to be held in place at the several points of adjustment in slot s. The incasing and adjusting features are substantially the same as shown in Figs. 12, 13, and 14. for plates b2 b2. rlhe folding-wings D D are also provided with J-hooked lugs d d, to act in combination with the cams C C at c e, for the purpose of operating folding-wings D D. (Shown plainly in Fig. 2.)

E E represent two folding-wings, hinged to female die B at ec, provided with plates b2 b2, hinged to folding-blades at b b.' Foldingblades b b and plates L2 l)2 are provided with lugs b: b and bi These lugs are connected by spiral spring b* b4, for the purpose of carrying foldingbladcs b b back to their place after they have performed their functions.

The pivoted folding` -bladcs b b are for the purpose of closing the finishing aps of the packet, as shown in Fig. 4. Folding-blades b b may be made adjustable, when it is desired to adapt the machine to fold different-sized packets, by means of adj ustable plates provided with screw and nut passing into corrugated slot in folding-wings E E, substantially as shown in Figs. 12 and 13, in which b represents the plate ineascd within the face of folding-wing E, and provided with screw q and nut q, which are adapted to pass through and to be held at the several points of adjustment in slot s, as shown in Figs. 12 and 13. Folding-wings E E are also provided with J-hooked lugs el d to act in combination with cams C C at c c, for the purpose of operating wings E E, as shown in Fig. 3.

F represents the cap, hinged to slide a at f, provided with lng j, attached to spiral spring t', for the purpose of carrying cap F back to stop H after it has performed its function. Cap F is also provided with handle f, for operating it by hand. (Jap F operates in holding down the overlapping ends of the wrapper, and combines with foldingwings E E and D D in creasing the folds of the wrapper, and combines with wings E E in pressing the finishing folds of the wrapper before they are closed down upon the base of the packet by foldingblades b b. Slides a a and plate bl may be at tached rigidly to die B and folding-wing E,

respectively, substantially in the same way v that slide p is attached to folding-wing D, as shown in Fig. 2, in which slide p is made a part of folding-wing D in the casting. The machine will then perform its functions in folding packages of uniform size; and it must be distinctly understood that I do not limit myself to a machine necessarily containing the adjustable features shown and described, nor to this exact mechanism.

C C represent the cams for operating the folding-wings E E and D D, and are provided with rollers c c. The operating-cams are attached rigidly to the transverse connectingpivot c by means ofthe operating-handle I, the ends of which pass through the hub of the cams G C intersecting pivot c.

G represents the gage,hinged to frame A at g, operated by hand, and is for the purpose of evening the ends of the candy sticks preparatory to folding the wrapper upon them, as shown by dotted lines in Fig. 1, conforming in shape to end of die B.

I represents the operating-handle, attached rigidly to the cams C C and pivot c.

Having thus described the construction of my machine and the uses and operation of the several parts, I will now describe its practical operation in making wrappers and packets consisting of a wrapper containing candy sticks or other small merchandise.

To fold a sheet of paper to make a wrapper, one of suitable size is placed in the female die B, as shown by dotted lines in Fig. 1,and con- IOO IIO

stage shown in Fig. 10, the wrapper being creased along the lines Z t, Z o, a l, so that it will stayin place ready for the next folding. Thev operating-handle is then dropped, throwing the folding-wings D D back and bringing the folding-wings E E to the positionshown in Fig. 3, and completing the folding of the wrapper, to be nested with others for future use, as shown in Fig. 11. Paste may be applied along the face n .o lof the wrapper before the last folding,when it is desired. Cap F is not used in the above-described process, nor are bladesb b and D D essential in this.` process. packet before removing. the wrapper from the machine in packing coffee, starch, and other small merchandise, the male die is removed immediately after the wings D D are raised to form the first fold, and in its place areput the goods to be; packed. Onel of the projecting ends of the wrapper is then folded down upon the base of the packet and creased upon blades D D along the lines k x, k x, and forming and creasing the folds of the wrapper along the lines a z, a z, as shown in Fig. 6,and.the other projecting end `is brought down -by means of cap F, and the folding completed in same manner as from this stage in making packets containing candy sticks, hereinafter described.

In making packet-s composed of a wrapper containingl candy sticks or other similarshaped goods, the Wrapper is rst placed in the female die B, the gage G then lowered upon it by hand, as shown in dotted lines, Fig. 1. v'Ihe candy sticks are then placed in the wrapper and evened against the V-shaped l head of the gage G, forming a configuration similar tothat'shown' in Fig. 5. GageG is then raised by hand to the position shown in Fig. 2. The projecting end vof the wrapper on the side of the die B next to operatinghandle I 4is then folded over upon the top of the candy by hand, and the opposite projecting end of the wrapper is brought down and held in place, overlapping the first, by means of cap F, Iwhich is operated, preferably, in this movement by the left hand. By raising 'operating-handle I the machine assumes the position vkshown in Fig. 2, folding thewrapper to that stage shown in Fig. 6, and creasing the wrapper by means of rigid blades D D and D2 D2 along the lines Z t, o n, n z,

and uw, as shown in Fig. 6. Then, by re- When it is desirable to complete the then folded down upon the base of the packet, one overlapping the other, by means of -the folding-blades b b, opera-tedby hand, as shown in Fig. 4, thus forming the completed packet, as shown in Fig. 8.
